Description

Technical Field

[0001] This application relates to the field of washer-dryer combo technology, specifically to a washer-dryer combo. Background Technology

[0002] A washer-dryer combo is a new type of intelligent washing machine that combines washing, spinning, and drying functions into one, based on a fully automatic washing machine with the addition of a drying function. As an indispensable appliance in modern family life, washer-dryer combos play a crucial role.

[0003] Currently, the air cooling dehumidification solution commonly used in washer-dryer combos involves continuously introducing fresh cooling water to ensure sufficient cooling energy for heat exchange with the humid air, thereby converting the humid air into water. This results in a serious waste of water resources.

[0004] Therefore, there is an urgent need for a washer-dryer combo machine that can save on cooling water usage. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and other issues.

[0006] The purpose of this invention is to make full use of the cooling energy of cooling water, thereby effectively saving the amount of cooling water used.

[0007] The purpose of this utility model is not limited to the purposes mentioned above. Those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0008] In some embodiments of this application, a washer-dryer combo is provided, the washer-dryer combo comprising:

[0009] Box;

[0010] An outer cylinder is disposed inside the box, and a water-holding cavity is formed inside the outer cylinder;

[0011] An inner cylinder is disposed within the water-holding cavity and is rotatable relative to the outer cylinder, forming a washing chamber within the inner cylinder;

[0012] A drying heater is installed inside the air duct to heat the air inside the air duct;

[0013] The cold storage unit is located in the same air duct as the drying heater. Air flows into the air duct from the air inlet and flows through the cold storage unit and the drying heater in sequence before flowing out from the air outlet.

[0014] The water inlet is connected to the cold storage tank and is used to supply cooling water to the cold storage tank;

[0015] The outlet is connected to the cold storage tank and is used to discharge the cooling water in the cold storage tank.

[0016] The cooler has a water storage chamber that can store cooling water supplied through the inlet.

[0017] The above technical solution has the following advantages or beneficial effects: a coolant is installed in the air duct where the drying heater is located, and the water inlet connected to the coolant can supply cooling water to the coolant, so that the cooling water supplied by the water inlet can stay in the water storage chamber. The cooling water in the water storage chamber can fully reduce the temperature of the coolant, so that the cooled coolant can effectively exchange heat with the hot and humid air to convert the hot and humid air into water. Thus, storing the cooling water supplied by the water inlet in the water storage chamber can fully utilize the cold energy of the cooling water, thereby effectively saving the amount of cooling water used.

[0018] In some embodiments of this application, a washer-dryer is provided, wherein the water inlet and the water outlet are both positioned at heights higher than the center of the cold storage unit.

[0019] The above technical solution has the following advantages or beneficial effects: by setting the height of both the inlet and outlet higher than the center height of the cold storage tank, the cooling water supplied through the inlet can be effectively retained in the cold storage tank, thereby making full use of the cooling water's cold energy and effectively saving the amount of cooling water used.

[0020] In some embodiments of this application, a washer-dryer combo is provided, wherein the water inlet is disposed on the top surface of the cold storage unit, and the water outlet is disposed on the side surface of the cold storage unit in the height direction.

[0021] The above technical solution has the following advantages or beneficial effects: by setting the water inlet on the top surface of the cold storage tank, the cooling water enters from the top of the cold storage tank, so that the cooling water can flow more evenly throughout the entire cold storage tank and reduce the dead corners through which the cooling water flows in the cold storage tank.

[0022] In some embodiments of this application, a washer-dryer combo is provided, wherein the water inlet and the water outlet are both located on the side of the cold storage unit in the height direction.

[0023] The above technical solution has the following advantages or beneficial effects: By setting both the inlet and outlet on the side of the coolant in the height direction, it is possible to avoid the formation of eddies or dead zones in the cooling water at the top or bottom of the coolant, thereby reducing the cooling water resistance and improving the smoothness and efficiency of the cooling water flow.

[0024] In some embodiments of this application, a washer-dryer is provided, wherein the height of the water inlet is higher than the height of the center of the cold storage unit, and the height of the water outlet is lower than the height of the center of the cold storage unit.

[0025] The washer-dryer combo also includes:

[0026] A valve is provided corresponding to the water outlet, and the valve is used to open and close the water outlet.

[0027] The above technical solution has the following advantages or beneficial effects: setting the water inlet at a height higher than the center of the cold storage tank and setting the water outlet at a height lower than the center of the cold storage tank allows the cooling water to flow from the top into the cold storage tank and gradually flow to the bottom using its own weight, which helps to uniformly cool the internal structure of the cold storage tank and improves the cooling efficiency.

[0028] In addition, the outlet is positioned at a height lower than the center of the coolant reservoir, and a valve is installed at the outlet to precisely adjust the flow rate of the cooling water as needed.

[0029] In some embodiments of this application, a washer-dryer combo is provided, wherein the water outlet is disposed on the bottom surface of the cold storage unit.

[0030] The above technical solution has the following advantages or beneficial effects: by setting the outlet on the bottom surface of the coolant, the cooling water flows out from the bottom of the coolant, so that the cooling water can use its own gravity to promote the natural flow of the cooling water and increase the flow rate of the cooling water.

[0031] In some embodiments of this application, a washer-dryer combo is provided, the washer-dryer combo further comprising:

[0032] A first temperature sensor is used to monitor the temperature of the cold storage unit;

[0033] The second temperature sensor is installed at the air inlet of the air duct to monitor the return air temperature of the air duct.

[0034] In some embodiments of this application, a washer-dryer combo is provided, the washer-dryer combo further comprising:

[0035] A first temperature sensor is used to monitor the temperature of the cold storage unit;

[0036] The second temperature sensor is installed at the air inlet of the air duct to monitor the return air temperature of the air duct.

[0037] and a control unit, wherein the control unit is configured to,

[0038] Calculate the difference between the return air temperature of the air duct and the temperature of the cold storage unit;

[0039] If the detected difference is below the first set temperature difference, then the valve is opened and cooling water is supplied to the cold storage tank.

[0040] When the difference is detected to reach or exceed the second set temperature difference, the valve is closed and the supply of cooling water to the cold storage tank is stopped, wherein the second set temperature difference is greater than the first set temperature difference.

[0041] The above technical solution has the following advantages or beneficial effects: A first temperature sensor and a second temperature sensor are installed in the washer-dryer combo. The first temperature sensor monitors the temperature of the coolant reservoir, and the second temperature sensor monitors the return air temperature of the air duct. The difference between the return air temperature of the air duct and the temperature of the coolant reservoir is calculated. The magnitude of this difference reflects the heat exchange efficiency between the humid air and the coolant reservoir. If the detected difference is below a first set temperature difference, it indicates that the heat exchange efficiency between the humid air and the coolant reservoir is low. Therefore, the valve is opened, and cooling water is supplied to the coolant reservoir to ensure sufficient cooling of the humid air. When the detected difference reaches or exceeds a second set temperature difference, it indicates that the heat exchange efficiency between the humid air and the coolant reservoir is high. Therefore, the valve is closed, and the supply of cooling water to the coolant reservoir is stopped, thereby effectively saving cooling water usage while ensuring cooling efficiency.

[0042] In some embodiments of this application, a washer-dryer is provided, wherein the water inlet flow rate is greater than the water outlet flow rate per unit time; if the difference is detected to be below a first set temperature difference, the valve is opened and cooling water is supplied to the cold storage tank, including:

[0043] When the difference is detected to be below the first set temperature difference, the valve is opened to allow the cooling water in the cold storage tank to flow out of the cold storage tank until the water level in the cold storage tank is detected to be below the set water level, then cooling water is supplied to the cold storage tank.

[0044] The above technical solution has the following advantages or beneficial effects: The inflow rate at the inlet is greater than the outflow rate at the outlet per unit time, ensuring that the cooling water in the cold storage unit continuously increases while the valve is opened and cooling water is supplied. When the temperature difference is detected to be below the first set temperature difference, indicating low heat exchange efficiency between the hot and humid air and the cold storage unit, the valve is opened to allow cooling water to flow out of the cold storage unit until the water level in the cold storage unit is detected to be below the set water level, indicating insufficient cooling water. Then, cooling water is supplied to the cold storage unit. Thus, by first discharging the higher-temperature cooling water and then introducing the lower-temperature cooling water, the amount of cooling water used can be greatly reduced.

[0045] In some embodiments of this application, a washer-dryer combo is provided, wherein the first set temperature difference is generated based on the return air temperature of the air duct; and / or

[0046] The second set temperature difference is generated based on the return air temperature of the air duct.

[0047] The above technical solution has the following advantages or beneficial effects: Linking the first set temperature difference value to the return air temperature of the duct allows for dynamic adjustment of the first set temperature difference value based on the real-time return air temperature of the duct, providing greater flexibility to adapt to different working environments and conditions. Linking the second set temperature difference value to the return air temperature of the duct also allows for dynamic adjustment of the second set temperature difference value based on the real-time return air temperature of the duct, providing greater flexibility to adapt to different working environments and conditions.

[0048] In some embodiments of this application, a washer-dryer combo is provided, wherein the air duct is a top air duct located above the inner drum.

[0049] In some embodiments of this application, a washer-dryer combo is provided, wherein the air duct is a bottom air duct located below the inner drum.

[0050] In some embodiments of this application, a washer-dryer combo is provided, wherein the coolant is a tube-fin heat exchanger.

[0051] The above technical solution has the following advantages or beneficial effects: In the washing and drying machine, the tube-fin heat exchanger is used as the cold storage unit. Due to the fin design of the tube-fin heat exchanger, the heat exchange area is significantly increased, thereby improving the heat exchange efficiency. This allows the cold storage unit to absorb and release heat more effectively, reducing energy waste.

[0052] The effects of the above-mentioned technical solutions are not limited to those mentioned above. Those skilled in the art can clearly understand other effects not mentioned from the description in the claims. Attached Figure Description

[0070] A washer-dryer combo is a new type of intelligent washing machine that combines washing, spinning, and drying functions into one, based on a fully automatic washing machine with the addition of a drying function. As an indispensable appliance in modern family life, washer-dryer combos play a crucial role.

[0071] Currently, the air cooling dehumidification solution commonly used in washer-dryer combos involves continuously introducing fresh cooling water to ensure sufficient cooling energy for heat exchange with the humid air, thereby converting the humid air into water. This results in a serious waste of water resources.

[0072] Therefore, there is an urgent need for a washer-dryer combo machine that can save on cooling water usage.

[0073] To solve the above-mentioned technical problems, this application proposes a washer-dryer combo machine.

[0093] Please see Figure 2 , Figure 2 This is a schematic diagram of the internal structure of a washer-dryer combo provided in an exemplary embodiment of this application.

[0094] In some embodiments of this application, the washer-dryer combo may include a drum assembly. The drum assembly may be disposed within the housing 1. The drum assembly may extend along the front-rear direction of the housing 1. A washing chamber 51 may be formed within the drum assembly. A drum opening may be formed on the front end face of the drum assembly. This drum opening communicates with the interior of the washing chamber 51. The drum opening is directly opposite the clothing inlet and the door 2 of the housing 1. When the door 2 is opened, clothing can be sequentially placed into the washing chamber 51 within the drum assembly through the clothing inlet on the front side of the housing 1 and the drum opening at the front end of the drum assembly for washing, spin-drying, and drying operations. When the housing 1 is closed, the housing 1 can simultaneously close the clothing inlet and the washing chamber 51.

[0095] In some embodiments of this application, the tubing assembly may include an outer tubing 4. The outer tubing 4 may be disposed inside the housing 1. The outer tubing 4 may be configured to contain washing water. The internal space of the outer tubing 4 can form a water-holding cavity 41. The water-holding cavity 41 can be used to hold washing liquids, such as water, detergent, fabric softener, etc.

[0096] In some embodiments of this application, the outer tub 4 can be made of aluminum alloy, which has excellent thermal conductivity and can dissipate heat quickly to avoid affecting the washer-dryer combo. The outer tub 4 can also be made of stainless steel, whose smooth surface makes it less prone to bacterial growth. The outer tub 4 provides some protection for the inner tub 5, preventing damage from external impacts during high-speed rotation. The outer tub 4 can also have sound insulation properties to reduce the significant noise generated by the washer-dryer combo during operation.

[0097] Please see Figure 3 , Figure 3 This is a schematic diagram of the internal structure of a washer-dryer combo provided in another exemplary embodiment of this application.

[0098] In some embodiments of this application, the tubing assembly may include an inner tubing 5. The inner tubing 5 may be disposed inside the outer tubing 4. A washing chamber 51 may be formed inside the inner tubing 5. The washing chamber 51 within the inner tubing 5 is used to hold clothes to be washed or dried. A water passage hole may be provided on the peripheral wall of the inner tubing 5. The washing chamber 51 can connect the space between the inner tubing 5 and the outer tubing 4 through the water passage hole. Washing liquid in the outer tubing 4 can enter the washing chamber 51 within the inner tubing 5 through the water passage hole; that is, washing liquid in the space between the inner tubing 5 and the outer tubing 4 can enter the washing chamber 51 within the inner tubing 5 through the water passage hole.

[0099] In some embodiments of this application, the inner drum 5 can be rotatably disposed inside the outer drum 4. When the inner drum 5 rotates relative to the outer drum 4, the inner drum 5 can drive the clothes to rotate relative to the outer drum 4, thereby realizing the washing and drying functions of the clothes in the washing chamber 51 of the inner drum 5, and improving the uniformity of washing, dehydration and drying of the clothes.

[0100] In some embodiments of this application, the inner drum 5 can be made of ceramic. Ceramic inner drums have high hardness and strong wear resistance, ensuring they are not easily damaged during long-term use. They can also withstand high temperatures and are not easily deformed. The inner drum 5 can also be made of stainless steel. Stainless steel inner drums are sturdy and durable, able to withstand significant pressure and impact, and have good corrosion resistance, making them rust-resistant. Alternatively, the inner drum 5 can be made of carbon fiber. Carbon fiber inner drums have extremely high strength and rigidity, ensuring stability during high-speed operation, and are also very lightweight, helping to reduce the overall weight of the washer-dryer combo.

[0101] In some embodiments of this application, the outer cylinder 4 and the inner cylinder 5 may also be arranged coaxially. The front ends of the outer cylinder 4 and the inner cylinder 5 may have openings arranged opposite to each other. The front end openings of the outer cylinder 4 and the inner cylinder 5 may be combined to form the opening of the cylinder assembly.

[0102] In some embodiments of this application, the inner tub 5 may be provided with a cleaning groove. The inner tub 5 may also be provided with ribs. Providing a cleaning groove and / or ribs inside the inner tub 5 helps to improve the shaking effect on the clothes, resulting in a more even distribution of the clothes.

[0103] In some embodiments of this application, the drum assembly may include a door seal ring. The door seal ring may be located at the front opening of the drum assembly. The door seal ring may be an annular structure. The door seal ring may be located between the clothing inlet and the opening of the drum assembly. The door seal ring can be used to seal the gap between the clothing inlet of the housing 1 and the opening of the drum assembly. Thus, the door seal ring can prevent washing water from the drum assembly from entering the interior of the housing 1.

[0104] Please see Figure 4 , Figure 4 This is a schematic diagram of the internal structure of a washer-dryer combo provided in another exemplary embodiment of this application.

[0105] In some embodiments of this application, the washer-dryer combo may include a drying heater 6. The drying heater 6 may include a heating wire. The heating wire may be made of a high-temperature alloy such as a nickel-chromium alloy. Because nickel-chromium alloys have good electrical conductivity, heat resistance, and corrosion resistance, the heating wire can maintain stable resistivity and mechanical properties at high temperatures.

[0106] In some embodiments of this application, the drying heater 6 may include a heating element. The heating element may be made of high-temperature resistant materials such as stainless steel or ceramic, so that the heating element can withstand the working conditions in a high-temperature environment. The outer shell material of the drying heater 6 may have good insulation and heat resistance to effectively prevent current leakage and fire hazards.

[0107] In some embodiments of this application, the drying heater 6 may be disposed within an air duct. The drying heater 6 can be used to heat the air within the air duct to a suitable temperature range.

[0108] In some embodiments of this application, the drying heater 6 can be positioned near the fan. By placing the drying heater 6 near the fan, not only can sufficient heating be ensured before the air enters the inner drum 5, improving drying efficiency, but heat loss is also reduced, improving energy efficiency. The heated, high-temperature air is blown by the fan onto the clothes in the inner drum 5, causing the moisture on the surface of the clothes to evaporate rapidly. By continuously supplying high-temperature air into the inner drum 5, the moisture in the clothes is expelled, ultimately achieving the purpose of drying the clothes.

[0109] In some embodiments of this application, the drying heater 6 can heat the air in the air duct to between 70°C and 80°C. In some embodiments of this application, the operating power of the drying heater 6 can be controlled to increase, thereby accelerating the drying process of clothes and shortening the drying time by increasing the air temperature.

[0110] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a cold storage device provided in an exemplary embodiment of this application.

[0111] In some embodiments of this application, the washer-dryer combo may include a cold storage unit. The cold storage unit absorbs and stores cold energy; when hot, humid air flows through it, it exchanges heat with the stored cold energy, thereby lowering the temperature of the hot, humid air. The cold storage unit may be made of materials with high thermal conductivity, corrosion resistance, and good mechanical properties, such as stainless steel, copper, and aluminum.

[0112] In some embodiments of this application, a plate heat exchanger can be selected as the cold storage unit. The plate heat exchanger consists of a set of rectangular thin metal heat transfer plates, through which heat is exchanged with hot and humid air.

[0113] In some embodiments of this application, a tube-fin heat exchanger can be selected as the cold storage unit. Because the tube-fin heat exchanger has a finned design, the heat exchange area is significantly increased, thereby improving heat exchange efficiency. This allows the cold storage unit to absorb and release heat more effectively, reducing energy waste.

[0114] In some embodiments of this application, the washer-dryer may include a water inlet. The water inlet may be connected to a coolant reservoir. The water inlet may be used to supply cooling water to the coolant reservoir.

[0115] In some embodiments of this application, the washer-dryer combo may include a water outlet. The water outlet may be connected to a coolant reservoir. The water outlet may be used to discharge cooling water from the coolant reservoir.

[0116] In some embodiments of this application, a water storage chamber may be formed within the coolant. The water storage chamber is capable of storing cooling water supplied through the inlet.

[0117] As can be seen from the above, a coolant storage unit is installed in the air duct where the drying heater is located. The water inlet connected to the coolant storage unit can supply cooling water to the coolant storage unit, so that the cooling water supplied by the water inlet can stay in the water storage chamber. The cooling water in the water storage chamber can effectively reduce the temperature of the coolant storage unit, so that the cooled coolant storage unit can effectively exchange heat with the hot and humid air to convert the hot and humid air into water. Thus, storing the cooling water supplied by the water inlet in the water storage chamber can make full use of the cooling energy of the cooling water, thereby effectively saving the amount of cooling water used.

[0118] In some embodiments of this application, the inlet height may be higher than the center height of the cold storage unit. The outlet height may be higher than the center height of the cold storage unit.

[0119] As can be seen from the above, setting the height of both the inlet and outlet of the water inlet higher than the center height of the coolant allows the cooling water supplied through the inlet to remain effectively in the coolant, thereby making full use of the cooling energy of the water and effectively saving the amount of cooling water used.

[0120] In some embodiments of this application, the water inlet may be located on the top surface of the cold storage tank. The water outlet may be located on the side of the cold storage tank in the height direction.

[0121] As can be seen from the above, placing the water inlet on the top surface of the coolant allows the cooling water to enter from the top of the coolant, thus enabling the cooling water to flow more evenly throughout the entire coolant and reducing dead zones in the coolant.

[0122] In some embodiments of this application, the water inlet can be located on the side of the cold storage unit along its height. The water outlet can be located on the side of the cold storage unit along its height. The height of the water inlet can be equal to the height of the water outlet. Alternatively, the height of the water inlet can be higher than the height of the water outlet.

[0123] As can be seen from the above, placing both the inlet and outlet on the side of the coolant along its height can prevent the cooling water from forming eddies or dead zones at the top or bottom of the coolant, thereby reducing cooling water resistance and improving the smoothness and efficiency of cooling water flow.

[0124] In some embodiments of this application, the water outlet may be located on the bottom surface of the cold storage tank.

[0125] As can be seen from the above, by placing the outlet on the bottom surface of the coolant, the cooling water flows out from the bottom of the coolant. In this way, the cooling water can use its own gravity to promote the natural outflow of the cooling water and increase the outflow rate of the cooling water.

[0126] In some embodiments of this application, there may be one or more water inlets. There may be one or more water outlets.

[0127] In some embodiments of this application, there may be two water outlets. One water outlet may be located on the bottom surface of the cold storage unit. The other water outlet may be located on the side surface of the cold storage unit along its height. A valve may be provided for the water outlet located on the bottom surface of the cold storage unit. A valve may also be provided for the water outlet located on the side surface of the cold storage unit.

[0128] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a cold storage device provided in another exemplary embodiment of this application.

[0129] In some embodiments of this application, the washer-dryer combo further includes a first temperature sensor. The first temperature sensor may be disposed on a coolant reservoir. The first temperature sensor can be used to monitor the temperature of the coolant reservoir. The first temperature sensor may be a thermistor sensor or a thermocouple sensor. This embodiment does not limit the specific type of the first temperature sensor.

[0130] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of a cold storage device provided in another exemplary embodiment of this application.

[0131] In some other embodiments of this application, the inlet may be positioned at a height higher than the center of the cold storage unit. The outlet may be positioned at a height lower than the center of the cold storage unit.

[0132] In some embodiments of this application, a valve can be provided corresponding to the water outlet, and the valve is used to open and close the water outlet. A solenoid valve can be used, where the movement of the valve core is controlled by the on / off state of an electromagnet, thereby opening and closing the water outlet. A proportional regulating valve can be used, which automatically adjusts the valve opening according to a set ratio or signal to achieve precise control of the drainage volume. A proportional regulating valve can include a closed state. A proportional regulating valve can include an open state. A proportional regulating valve can include a partially open / partially closed state. A proportional regulating valve can be used to control the flow rate and speed of drainage.

[0133] As can be seen from the above, setting the height of the water inlet higher than the center of the cold storage tank and the height of the water outlet lower than the center of the cold storage tank allows the cooling water to flow from the top into the cold storage tank and gradually flow to the bottom using its own weight. This helps to evenly cool the internal structure of the cold storage tank and improves the cooling efficiency.

[0134] In addition, the outlet is positioned at a height lower than the center of the coolant reservoir, and a valve is installed at the outlet to precisely adjust the flow rate of the cooling water as needed.

[0135] In some embodiments of this application, the air duct may be a top air duct. The top air duct may be located above the inner cylinder.

[0136] Please see Figure 8 , Figure 8 This is a schematic diagram of the location of the cold storage device and the airflow direction provided in an exemplary embodiment of this application.

[0137] In some embodiments of this application, the cold storage unit can be disposed in the same air duct as the drying heater 6. If the drying heater 6 is disposed in the top air duct, the cold storage unit is also disposed in the top air duct. Air flows into the air duct from the air inlet of the top air duct, and flows through the cold storage unit and the drying heater 6 in sequence before flowing out from the air outlet of the top air duct.

[0138] In some embodiments of this application, the washer-dryer combo also includes a second temperature sensor. The second temperature sensor can be located at the air inlet of the top air duct and is used to monitor the return air temperature of the top air duct. The second temperature sensor can be a thermistor sensor. The second temperature sensor can also be a thermocouple sensor. This embodiment does not limit the specific type of the second temperature sensor.

[0139] In some other embodiments of this application, the air duct may be a bottom air duct. The bottom air duct may be located above the inner cylinder.

[0140] Please see Figure 9 , Figure 9 This is a schematic diagram of the location of the cold storage unit and the airflow direction provided in another exemplary embodiment of this application.

[0141] In some embodiments of this application, the cold storage unit can be disposed in the same air duct as the drying heater 6. If the drying heater 6 is disposed in the bottom air duct, the cold storage unit is also disposed in the bottom air duct. Air flows into the air duct from the air inlet of the bottom air duct, and flows through the cold storage unit and the drying heater 6 in sequence before flowing out from the air outlet of the bottom air duct.

[0142] In some embodiments of this application, the washer-dryer combo also includes a second temperature sensor. The second temperature sensor can be located at the air inlet of the bottom air duct to monitor the return air temperature of the bottom air duct.

[0143] In some embodiments of this application, the washer-dryer combo also includes a control unit.

[0144] In some embodiments of this application, the control unit may be electrically connected to the first temperature sensor, the second temperature sensor, and the valve, respectively.

[0145] Please see Figure 10 , Figure 10 This is a flowchart illustrating the steps that the control unit can execute, provided in an exemplary embodiment of this application.

[0146] In some embodiments of this application, the washer-dryer combo further includes a first temperature sensor and a second temperature sensor, wherein the first temperature sensor is used to monitor the temperature of the coolant, and the second temperature sensor is disposed at the air inlet of the air duct to monitor the return air temperature of the air duct; the control unit can be configured to perform the following steps S110-S170:

[0147] S110, calculate the difference between the return air temperature of the air duct and the temperature of the cold storage unit.

[0148] S120, determine whether the difference is below the first set temperature difference.

[0149] S130, if the result is negative, then proceed to S120.

[0150] S140, if the determination is yes, then control the opening of the valve and control the supply of cooling water to the cold storage tank.

[0151] S150, determine whether the difference reaches or exceeds the second set temperature difference value.

[0152] S160, if the determination is yes, then control to close the valve and control to stop supplying cooling water to the cold storage tank, wherein the second set temperature difference is greater than the first set temperature difference.

[0153] S170, if the result is negative, then proceed to S140.

[0154] The following sections will elaborate on each of the above steps.

[0155] In S110, in some embodiments of this application, the difference may be equal to the return air temperature of the duct minus the temperature of the cold storage unit.

[0156] The magnitude of the difference reflects the heat exchange efficiency between the hot, humid air and the coolant. The difference is directly proportional to the heat exchange efficiency. A smaller difference indicates lower heat exchange efficiency between the hot, humid air and the coolant, while a larger difference indicates higher heat exchange efficiency.

[0157] In S120, in some embodiments of this application, the first set temperature difference value can be a set constant.

[0158] In other embodiments of this application, the first set temperature difference can be a dependent variable with other parameters as independent variables. For example, the first set temperature difference can be a dependent variable of the return air temperature of the duct. The first set temperature difference can be generated based on the return air temperature of the duct.

[0159] As can be seen from the above, by associating the first set temperature difference with the return air temperature of the air duct, the first set temperature difference can be dynamically adjusted according to the real-time return air temperature of the air duct, making it more flexible to adapt to different working environments and conditions.

[0160] For example, the first set temperature difference can also be a dependent variable of the temperature of the cold storage unit. The first set temperature difference can be generated based on the temperature of the cold storage unit.

[0161] As can be seen from the above, by associating the first set temperature difference with the temperature of the cold storage unit, the first set temperature difference can be dynamically adjusted according to the real-time temperature of the cold storage unit, making it more flexible to adapt to different working environments and conditions.

[0162] In S130, if the difference is not below the first set temperature difference, that is, the difference is above the first set temperature difference, then the step of "determining whether the difference is below the first set temperature difference" continues to be executed.

[0163] In S140, if the difference is determined to be below the first set temperature difference, it indicates that the heat exchange efficiency between the hot and humid air and the cold storage is low. In this case, the valve is opened and cooling water is supplied to the cold storage to ensure that the hot and humid air is adequately cooled.

[0164] In S150, in some embodiments of this application, the second set temperature difference value can be a set constant.

[0165] In other embodiments of this application, the second set temperature difference can be a dependent variable with other parameters as independent variables. For example, the second set temperature difference can be a dependent variable of the return air temperature of the duct. The second set temperature difference can be generated based on the return air temperature of the duct.

[0166] As can be seen from the above, by associating the second set temperature difference with the return air temperature of the air duct, the second set temperature difference can be dynamically adjusted according to the real-time return air temperature of the air duct, making it more flexible to adapt to different working environments and conditions.

[0167] For example, the second set temperature difference can also be a dependent variable of the temperature of the cold storage unit. The second set temperature difference can be generated based on the temperature of the cold storage unit.

[0168] As can be seen from the above, by associating the second set temperature difference with the temperature of the cold storage unit, the second set temperature difference can be dynamically adjusted according to the real-time temperature of the cold storage unit, making it more flexible to adapt to different working environments and conditions.

[0169] In S160, if the difference value reaches or exceeds the second set temperature difference value, it indicates that the heat exchange efficiency between the hot and humid air and the cold storage is high. Then, the valve is closed and the supply of cooling water to the cold storage is stopped, thereby effectively saving the amount of cooling water used while ensuring cooling efficiency.

[0170] In some embodiments of this application, the second set temperature difference can be greater than the first set temperature difference.

[0171] In S170, if it is determined that the difference does not reach the second set temperature difference, that is, the difference is below the second set temperature difference, then the steps of "controlling the opening of the valve and controlling the supply of cooling water to the cold storage tank" continue to be executed.

[0172] In some embodiments of this application, the inflow rate of the inlet is greater than the outflow rate of the outlet per unit time; if the difference is detected to be below a first set temperature difference, the steps of controlling the valve to open and controlling the supply of cooling water to the cold storage tank include:

[0173] When the detected temperature difference is below the first set temperature difference, the valve is opened to allow the cooling water in the cold storage tank to flow out of the cold storage tank until the water level in the cold storage tank is detected to be below the set water level, at which point the cooling water is supplied to the cold storage tank.

[0174] Furthermore, ensuring that the inflow rate at the inlet is greater than the outflow rate at the outlet within a unit of time guarantees a continuous increase in cooling water within the cold storage unit while the valve is opened and cooling water is supplied. When the temperature difference is detected to be below a first set temperature difference, it indicates low heat exchange efficiency between the hot, humid air and the cold storage unit. When the temperature difference is detected to be below the first set temperature difference, the valve is opened to allow cooling water to flow out of the cold storage unit. Cooling water is then supplied to the cold storage unit only when the water level is detected to be below a set water level, indicating insufficient cooling water remaining in the unit.

[0175] Therefore, by first draining the higher-temperature cooling water and then introducing the lower-temperature cooling water into the cold storage tank, the amount of cooling water used can be greatly reduced.

[0176] Similarly, when the temperature difference reaches or exceeds the second set temperature difference, it indicates that the heat exchange efficiency between the hot and humid air and the cold storage unit is relatively high. In this case, the valve is closed and the supply of cooling water to the cold storage unit is stopped, thereby effectively saving cooling water usage while ensuring cooling efficiency.
